step one, excavating branch pipe grooves and rainwater opening earthwork: the construction of the gutter inlet and the branch pipe is carried out after the acceptance of a road bed is qualified, a line is required to be arranged according to the sideline elevation in a design drawing for digging a groove, the position, the direction and the elevation are controlled, and then a gutter inlet central line pile is determined according to the design sideline and the branch pipe position of a road so that the long side of the gutter inlet is required to be overlapped with the road side (except for the part of a bend); according to the center line of the gutter inlet, a fertilizer groove is reserved for trench excavation, if the position of the gutter inlet has an error, the position is corrected by taking a branch pipe as a standard, the position is parallel to the roadside, the trench is excavated to the designed depth, and an excavator is adopted for excavation;

step two, sand cushion layer: the pipe base adopts a sand foundation, and when the bottom elevation of the slotted groove of the pipeline is positioned in the current soil layer, the original soil cannot be disturbed during slotting;

step three, connecting and installing pipelines: the pipeline is constructed in sections, and the pipes are arranged beside the groove along the pipeline laying direction; the pipe orifice part is subjected to sealing protection for long connection and installation interval time and each engineering work receiving; the pipeline is moved into the groove by an elastic pipe laying method after being connected in sections at the groove edge; when the pipeline is moved into the groove, the pipe cannot be damaged, obvious scratches cannot be formed on the surface of the pipe, and the pipe is lowered by adopting a non-metal rope; when the pipeline is installed, the center and the elevation of the pipe joint are adjusted correctly section by section, two sections of pipes need to be centered, the installed pipe joint needs to be retested, and the construction of the next procedure can be carried out after the pipe joint is qualified; cleaning sundries of the pipeline at any time during installation, and temporarily plugging two ends of the pipeline when the pipeline is temporarily stopped to be installed;

step four, building the gutter inlet: the construction of the gutter inlet is carried out after the laying of the branch pipe pipeline is finished, firstly, bottom plate concrete is poured, concrete is adopted for paving, and after the design requirement is met, a well wall is constructed; the well wall cement mortar masonry brick is constructed, during construction, a line is hung according to the position of a well wall, a layer of the well wall is firstly built, a flat joint is scraped along with the building, and a fertilizer groove outside the wall is timely backfilled and tamped when the building height is 30 cm; building a well wall, wherein mortar is full and pointing is carried out along with building; the rainwater pipe and the ring wall are full of mortar, two leather brick tickets are arranged on the top of the pipe, and the well wall is built to the required elevation; building until the rainwater branch pipe is full of horizontal mortar, when the branch pipe is fully covered by the brick building, the periphery of the gateway is tightly smeared with the mortar, no gap exists, building a semicircular brick block on the top of the pipe, and enabling the pipe opening to be flush with the well wall; the interior of the catch basin 1 is kept clean, the building and the cleaning are carried out during the building, and cement mortar is used for smearing out a rainwater pipe opening to form a flood slope at the bottom of the well.

The implementation principle of the gutter inlet structure and the construction method thereof in the embodiment of the application is as follows: when sewage in the rainwater port is cleaned, the rainwater grate 11 is firstly opened, and the opening and closing valve 311 is controlled to be opened by the opening and closing assembly 6 after the rainwater grate 11 is taken out, so that the sewage deodorant in the tank body 3 flows to the spray head 51 along the liquid discharge pipe 31 and is sprayed into the sedimentation well 2, and after the sewage deodorant drops into the sewage, odor emitted by the sewage can be inhibited, and the odor smelled by a worker when the sewage in the rainwater port is cleaned is reduced to a certain extent; after the rainwater is cleaned, the rainwater grate 11 is covered on the rainwater well 1 again, the opening and closing assembly 6 can automatically close the opening and closing valve 311, and the deodorant in the tank body 3 cannot be sprayed out; when sewage needs to be cleaned, the sewage deodorant can be sprayed out, and waste is avoided to a certain extent.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
